🤖 What is MCP?

The Model Context Protocol (MCP) is an open protocol that enables AI assistants to securely connect to external data sources and tools. Think of it as a standardized way for AI models like Claude to interact with your applications and services.

Key Concepts:

• MCP Server: Provides tools and data (this project!)
• MCP Client: AI assistant that uses the tools (e.g., Claude Desktop)
• Tools: Functions that the AI can call to perform actions
• Protocol: Standardized communication format using JSON-RPC

GitInsight-MCP implements an MCP server that exposes your GitHub profile data to AI assistants, allowing them to answer questions about your repositories, analyze your coding patterns, and generate portfolio insights. I Built This Project

I created GitInsight-MCP to:

🔍 Explore the MCP Inspector - Wanted to see how MCP servers work and test them interactively
🛠️ Discover New MCP Tools - Learn about the Model Context Protocol ecosystem
🤖 Collaborate with Claude AI - Built entirely using Claude as a coding partner
📚 Learn by Doing - Hands-on experience with TypeScript, Node.js, and GitHub API
🚀 Create Something Useful - A practical tool that actually works with my GitHub profile

This is a learning project showcasing:

• AI-Assisted Development - Every line of code written with Claude
• Modern Backend Stack - TypeScript, Node.js, MCP SDK
• Real API Integration - GitHub Octokit, caching, error handling
• Production Quality - Full documentation, proper architecture

Perfect for:

• Developers exploring MCP and AI-assisted coding
• Learning how to build tools that AI assistants can use
• Understanding the Model Context Protocol specification
• DevOps Engineers wanting to showcase AI integration skills
• Full Stack Developers building MCP servers
• Anyone creating an intelligent portfolio assistant

🐛 Troubleshooting

Issue: "Missing required environment variables"

Solution: Create a `.env` file with `GITHUB_TOKEN` and `GITHUB_USERNAME`

Issue: "GitHub API rate limit exceeded"

Solution:

• Wait for the rate limit to reset (shown in server logs)
• Use caching (`use_cache: true`)
• Authenticate with a valid token (increases limit to 5000/hour)

Issue: "Invalid GitHub token"

Solution:

• Generate a new token at https://github.com/settings/tokens
• Ensure scopes include: `repo`, `read:user`
• Check for typos in your `.env` file

Issue: Claude Desktop doesn't show the server

Solution:

• Check the config file path is correct for your OS
• Use absolute paths in `claude_desktop_config.json`
• Restart Claude Desktop completely
• Check Claude Desktop logs for errors

Issue: Server crashes on startup

Solution:

• Run `npm run build` first
• Check Node.js version is 18+
• Verify all dependencies installed: `npm install`
